The objective of this paper is to review the theoretical basis and clinical application of electrical impedance plethysmography in the noninvasive evaluation of peripheral arterial and venous disease. Theoretical, experimental and clinical studies have now demonstrated a direct relationship between electrical impedance changes and limb volume changes. Potential sources of error have also been identified. This has led to the development of clinical tests based on impedance plethysmography for the detection of peripheral arterial disease, venous insufficiency and venous outflow obstruction. Impedance plethysmography, using the method of venous occlusion, is presently the most commonly employed noninvasive method for the detection of deep venous thrombosis.
本文的目的是综述电阻抗容积描记法在周围动脉和静脉疾病无创评估中的理论基础及临床应用。理论、实验和临床研究现已证实电阻抗变化与肢体容积变化之间存在直接关系。同时也已确定了潜在的误差来源。这促使基于电阻抗容积描记法开发出用于检测周围动脉疾病、静脉功能不全和静脉流出道梗阻的临床试验。采用静脉阻断法的电阻抗容积描记法目前是检测深静脉血栓形成最常用的无创方法。
